I'm sorry, but I'm working also as web designer and I don't like some parts from your website. You can improve: The right menu background, it is not good that king of gradient or picture I don't know what you used, I didn't checked the source code. I can see another mistake in the left part, the second shadow it's for nothing there because you have one for the header part and the second one must be after that black text.
You should fix this problems if you want. Also I saw a small mistake in the right side in footer, there appears ' " ' on the orange background.

I don't want to say that I don't like he website because the content is the main idea, but in the design part you have these problems.
